Specification of Letters Patent.

Patented May 8, 1906.

Application filed December 4,1905. Serial No. 290,242.

To all whom it may concern.-

Be it known that I, GEORGE A. GOULD, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Molds for Manufacturing Bricks and Artificial Stone, of which the following is a specification.

This invention relates to a new and useful mold for the construction of bricks, artificial stone, blocks, and the like from clay, cement, or other suitable material; and the object thereof is to provide a mold in a manner hereinafter set forth which will permit of great pressure upon the material employed during the formation of the brick, stone, or block without distorting the mold and, furthermore, will enable a very convenient and quick operation to be had during the act of molding.

The invention further aims to provide a mold for the purpose set forth which shall be simple in its construction, having the elements thereof suitably interlocked in an automatic manner when closing the mold, readily and quickly opened, so that the molded article can be conveniently removed, strong, durable, eflicient in its use, and comparatively inexpensive to manufacture.

With the foregoing and other objects in I view the invention consists of the novel construction, combination, and arrangement of parts hereinafter more specifically described, and illustrated in the accompanying drawings, which form a part of this specification and wherein is shown the preferred embodiment of the invention; but it is to be under stood that changes, variations, and modifications can be resorted to which come within the scope of the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, wherein like reference characters denote corresponding parts throughout both views,and in which- Figure 1 is a perspective view of the mold when opened, and Fig. 2 is a like view with the mold closed.

A mold for the purpose set forth in accordance with this invention comprises a base 1, formed, preferably, of two or more sections suitably spaced apart; but, if desired, the base 1 can be formed of a single piece of suitable material. The base 1 is of much greater width than the width of the mold when the latter is set up, and the said base 1 projects forwardly at the bottom of the mold, and the said projecting portion 2 of the base 1 acts as a means for supporting the hinged front wall 3 of the mold and, furthermore, constitutes a means for supporting the lower sections 4 of the'hinges which constitute the connection between the base and the front wall 3, the upper section of the hinges being indicated by the reference character 5 and secured to the front face of the wall 3, at the bottom thereof.

The holdfast devices for securing the hinges to the base and the wall 3 are indicated by the reference character 6.

The rear wall of the mold is indicated by the reference character 7, said wall being fixed at its bottom to the base 1.

The side walls of the mold are indicated by the reference characters 8 9 and are hinged to the rear wall 7 in such a manner that the said side walls 8 9 can be swung rearwardly to open position, but when closed the said side walls 8 9 will abut against the side edges of the rear wall 7 and the rear edges of the. said side walls 8 and 9 will lie flush with the outer face of the rear wall 7 The connection between the side walls 8 9 and the rear wall 7 is had through the medium of a pair of hinges and which are adapted to suspend the side walls 8 9.

The sections of the hinges for connecting as well as suspending the side walls 8 9 to and from the rear wall 7 are indicated by the reference characters 10 11, said sections 10 being secured by the holdfast devices 12 to the rear wall 7, and the said sections 10 project laterally from the side edges of the rear wall 7, thereby suspending the side walls 8 9 when the latter are opened a suitable distance from the side edges of the rear wall 7. By sucn an arrangement it permits the side walls 8 9 when swung to closure position to abut against the side edges of the rear wall 7 and make a substantially tight joint. The sections 11 of the hinges which connect the side walls 8 9 to the rear wall 7 are secured to the side walls 8 9 through the medium of the holdfast devices 13. Each of the side walls 8 9 at its upper outer corner is provided with a forwardly-extending protuberance 14 of greater width than the width of its respective side wall, thereby forming a longitudinally-extending shoulder 15, which when the mold is closed lies in the ath of the front wall 3, so as to prevent sai front wall 3 from being opened until the side walls 8 9 are released from closure position. A look, to be .positionthat is to say, the

hereinafter referred to, for retaining said side walls in closure position is employed.

The lock for retaining the side walls 8 9 in closure position consists of a pair of shouldered spring-catches 16 17, which are secured V to engage the side walls 8 9, so as to prevent 1 the said side walls 8 9 from being moved from closure position until the said spring-catches 16 17 are moved out of the path of the said side walls 8 9.

By providing the side walls 8 9 with the protuberances 14, so as to form the shoulder 15, and by securing to the front wall the shouldered spring-catches 16 17 the side walls 8 9 and front wall 3 are adapted to interlock one with the other when the mold is closed, the interlocking being what may be termed in an automatic manner, for the reason that the protuberances 14 position themselves in the path of the front wall 3 when the side walls are swung to closure position, and as the spring-catches are beveled the said side walls will ride over the beveled faces of the catches, so that after they pass said beveled portion the catches will spring to locking shoulders of the spring-catches will be positioned against the outer face of the side walls 8 9.

The mold is provided with a removable pallet (indicated by the reference character 18) which constitutes aremovable base-plate.

The manner of using the mold is as follows: The pallet 18 of a proper size is placed in the bottom of the mold and the side walls and front wall folded together until the springcatches spring to locking position, said s ring-catches, in connection with the shoulered protuberances, locking the mold. The mold is then filled level with the necessary material. The mold and the contents thereof are then placed under the plunger of a machine which is forced down into the mold, so that the contents thereof are pressed into the form and size of the brick, stone, or block required. The spring catches are then released, which admits of the sides and front wall of the mold being swung away from the brick, stone, or block. The latter can then be removed by means of'the pallet which supports it. The pallet also facilitates the handling of the bricks, stone, or blocks after their removal from the mold.

The walls of the mold are preferably constructed of metal, so that the inner faces of the walls will be very smooth, which imparts a similar surface to the molded article, yet the walls of the mold can be constructed of any suitable material. The pallet is preferably formed of wood; but any other suitable material can be employed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A mold consisting of a base of greater width than the mold proper and projecting forwardly from the mold, a front wall hinged to the projecting portion of the'base, a rear wall fixed to the base, a pair of side walls hinged to said fixed wall, each of said side walls having the front thereof at its top provided with a forwardly-projecting protuberance having an inwardly-extending shoulder adapted when the mold is closed to be positioned in the path of the front wall, and spring-catches carried by the front wall and adapted to engage the side walls below the protuberances for automatically locking said side and front walls in position, said shouldered protuberances and spring-catches constituting a lock for retaining the mold in its closed position.
